Windows Phone 7 Hiding the Application Bar

Question

I would like to be able to press a button to disable the menu bar in my application. If you go

menubar.IsVisible = false;

it throws a null reference exception. The menu bar is declared in XAML.

Anyone know if its possible to hide it on the fly like this?

Answer 1

You can access this as a static member on ApplicationBar. i.e.

ApplicationBar.IsVisible = true/false;

Some background here on why ApplicationBar doesn't play like normal silverlight elements.
